Inspired by Myles’ post about helical gears. This is a 30T gear with 32 mm pitch diameter.
Hey Dave - have you ever modeled a wheelchair?
Not a whole one. I’ve modeled parts of a wheelchair for various things. I did the foot plate hanger when I was modeling the heel strap prototype and I’ve done part of the frame of the same chair for another need. I suppose I should finish up the second one. Why do you ask?
No worries, I’m making a wheelchair-accessible drawing and there aren’t any great wheelchairs on warehouse.
Planning to make some 3D to 2D wheelchairs (top view, side view) to show turning space requirements on floor plan, etc. Also planning to make them scaled drawings and add them to my LO scrapbook.
I see. For an application like that you probably need very simple models, right? Nothing anywhere close to as detailed as what I’ve already done.
Correct, I think I’ve found a WH model that will work, it just requires some cleanup after using Curic Make2D. It is just so hard working with WH models that aren’t solid and component-based…
Look up Bradley Company in 3D Warehouse. They are mostly showing products for ADA compliance, but I discovered they had a wheel chair and some other symbols in their example models.
That’s a hospital clunker.

@TheOnlyAaron’s Grasshopper WIP. Most of the bigger parts are done.
I was going to record a video of the modeling process but decided I wouldn’t inflict that on anyone.
One more of the Grasshopper for tonight. Eccentric, eccentric strap, valve link and timing the vale is all that’s left. Working out the correct positions for all the moving parts is almost more interesting that modeling the parts.
A few screws and cotters left to make but otherwise finished.
I decided to give the engine something to do and added Elmer’s centrifugal pump.
Here’s a funny little steam engine called Baldy. A spherical piston. Steam inlet is the copper colored thing in the back. The steam valve is built into the crankshaft. For reference, the flywheel is 1-1/4 in. dia.
I decided to embellish this simple model a little.
A little 3D printing project. I need some clamps to fit on two different sizes of tube. I modeled the larger one first and then instead of modifying it to make the smaller one, I just modeled a filler. The slicer combines the two components into a single one. The knobs and other bits were stuff I had in a drawer.
We had new European-style tilt and turn windows installed recently. I decided to add some little clips to help keep the windows over the kitchen sink open. This is a test to see how well they work. They are about 29mm tall. Mounted with “The Mining’s” VHB tape which will hold tenaciously but won’t wreck the finish if I want to remove it.
After watching @TysonK’s videos on modeling screw threads, I decided to model and print another test. This time it’s 1/2-13 class 2 threads. The hex nut is 3/4 in. across the flats. The tap for the internal threads is on the left.
More 3D print stuff.
A couple of arms to allow the smaller diameter tube to be clamped to the larger one in the back. The channel around the front hole is for a zip tie.
Assembled
Arm
The arms are on the printer now.
The C-shaped clips on the ends are a revision of the ones shown on this bag. Made smaller to fit the smaller tube.
